Description

Technical Field

[0001] This invention relates to the field of lock technology, and in particular to an intelligent locker lock. Background Technology

[0002] Traditional electronic locks mostly use electromagnets for their clutch mechanism. This structure has low security and can be easily cracked by using magnetic objects such as magnets. At the same time, solenoid valve structures generally have the disadvantages of complex structure and unstable function, which can easily lead to situations where the lock or unlock is not properly engaged.

[0003] An existing electronic combination lock includes a lock housing, a knob, a limit pin, an electronically controlled limit assembly, and a circuit board. The lock housing has a mounting cavity with a lock hole. The knob is installed in the lock hole and has a limit groove on its circumferential surface. The limit pin is located in the mounting cavity and is movably fitted on the circumferential surface of the knob. The electronically controlled limit assembly includes a motor, a stop block, and a first spring located in the mounting cavity. The motor has a rotating shaft. The stop block includes a connecting part and a limiting part. The connecting part consists of two baffles sleeved on the rotating shaft, and the limiting part is opposite to the limit pin. The first spring is sleeved on the rotating shaft and located between the two baffles. The circumferential surface of the rotating shaft protrudes to form a protrusion into which the first spring is embedded. When the motor is working, it compresses the first spring through its protrusion to drive the stop block to limit or release the radial movement of the limit pin.

[0004] Electronic unlocking works by starting the motor and rotating the shaft after the correct password is entered. A protrusion on the shaft compresses the first spring, causing it to move to the right. This compresses the stop block, releasing the limit pin. When the user rotates the knob, the limit pin moves upwards along the slide, freeing the knob from being locked by the limit pin. Furthermore, the upward movement of the limit pin compresses the swing plate, triggering the microswitch to receive the unlocking signal, thus unlocking successfully. However, this type of electronic lock has the following drawbacks:

[0005] For example, when the user turns the knob, the limit pin needs to move upward to squeeze the swing plate to rotate and trigger the micro switch to receive the unlocking signal, and the lock will be successfully unlocked. This makes the whole unlocking process complicated, and the installation accuracy of the limit pin and the swing plate in the lock body is required to be high. If the limit pin is resisted when it moves upward and cannot swing, it will cause the lock to fail to unlock and affect the use of the lock.

[0006] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention

[0007] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide an intelligent locker lock. Through the structural design and coordination between the lock tongue mechanism, knob, mechanical unlocking mechanism and electronic unlocking mechanism, it effectively solves the problems of complex unlocking process and high installation accuracy requirements of limit pins and swing plates in the lock body in traditional technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A smart locker lock includes:

[0010] Lock body;

[0011] A latch mechanism is provided on the lock body. The latch mechanism includes a rotating shaft, a movable pin, and a latch. The rotating shaft is provided with a mounting groove that extends axially along the rotating shaft. The movable pin is movably disposed in the mounting groove so that one end of the movable pin protrudes outside the rotating shaft. The latch is connected to one end of the rotating shaft and protrudes outside the lock body.

[0012] A knob, the outside of which is provided with a magnet for cooperating with an unlocking or locking sensing element; the knob is rotatably connected to the other end of a rotating shaft, and the knob controls the rotating shaft to selectively rotate, thereby driving the bolt to rotate to achieve locking and unlocking;

[0013] A mechanical unlocking mechanism is located beside the bolt mechanism; the mechanical unlocking mechanism includes a lock cylinder and a lever, the lever being selectively abutted against the outside of a rotating shaft via the lock cylinder; the lock cylinder is rotatably mounted on the lock body, such that the end of the lever near the rotating shaft is close to or away from the rotating shaft;

[0014] An electronic unlocking mechanism is installed on the lock body. The electronic unlocking mechanism includes an NFC antenna board, a PCB board, a motor, a cam, a slider, an unlocking and locking sensing element, and a locking and closing sensing element.

[0015] The motor drives the cam to rotate and is electrically connected to the PCB board; the slider is disposed between the rotating shaft and the cam, and an elastic element is connected between the cam and the slider, allowing the slider to selectively move back and forth; wherein, one side of the slider abuts against the rotating shaft;

[0016] The NFC antenna board is electrically connected to the PCB board; the unlocking and locking sensing elements are disposed on the PCB board and located below the knob, and the PCB board is electrically connected to the unlocking and locking sensing elements.

[0017] In the locked state, the lever and slider are respectively abutted against the outside of the rotating shaft, and one end of the movable pin abuts against the lever; the magnet is close to the trigger locking sensing element, so that the knob cannot drive the rotating shaft to rotate;

[0018] When the mechanical key is in the unlocked state, the lock cylinder is rotated by the key, so that one end of the linkage lever moves away from the rotating shaft, causing one end of the movable pin to disengage from the lever. Turning the knob unlocks the lock, and the rotating shaft can rotate relative to the lock seat.

[0019] In the electronic unlocking state, the motor receives a control signal and drives the cam to rotate. At this time, turning the knob to unlock causes the rotating shaft to rotate. The movable pin moves backward under the rotational force of the rotating shaft, pushing the slider backward so that the magnet approaches the unlocking and locking sensing element.

[0020] As a preferred embodiment, the lower end of the lock cylinder is provided with a protrusion, and the lever includes a left connecting section and a right connecting section. The left connecting section is provided with a movable groove on the side near the protrusion, and the movable groove has a left mating end and a right mating end.

[0021] The right connecting section is provided with a first arc-shaped abutment part for abutting and cooperating with the outer periphery of the rotating shaft and a stop part for abutting and cooperating with the front end of the movable pin on the side facing the rotating shaft. The first arc-shaped abutment part is recessed on the right connecting section, and the stop part is located beside the first arc-shaped abutment part.

[0022] When the lock cylinder rotates, the protrusion slides against the right mating end, causing the right connecting section to shift to the left, so that the first arc-shaped abutment and the stop part move away from the rotating shaft and the movable pin respectively. By utilizing the cooperation between the protrusion and the movable groove, the lever is moved to form a locking or unlocking mechanism for the rotating shaft and the movable pin. When locked, the first arc-shaped abutment and the stop part are used to position and lock the rotating shaft and the movable pin. Its structure is ingeniously designed, and the lock is reliable and highly secure.

[0023] As a preferred embodiment, the cam includes a first front connecting section and a first rear connecting section, the output end of the motor is connected to the first rear connecting section, and the first front connecting section includes a main body and a limiting part extending from one side of the main body;

[0024] The slider includes a second front connecting section and a second rear connecting section. The second rear connecting section extends from the rear end of the second front connecting section. The second front connecting section is recessed with a second arc-shaped abutment portion, which faces the mounting groove.

[0025] In the electronic unlocking state, the limiting part is away from the second rear connecting section, and the second annular connecting part is away from the rotating shaft; in the electronic locking state, the second arc-shaped abutting part abuts against the rear side of the mounting groove, and the second rear connecting section abuts against the limiting part; in the locking state, it cooperates with the lever to form a double positioning and locking of the rotating shaft and the movable pin.

[0026] As a preferred embodiment, the main body is further provided with a positioning hole, in which a steel ball is disposed. One end of the elastic element abuts against the steel ball, and the other end of the elastic element abuts against the rear side of the second front connecting section.

[0027] As a preferred embodiment, the rotating shaft includes a shaft body and a rotating part and a connecting part disposed on the shaft body. The knob is rotatably connected to the rotating part, and the locking tongue is locked to the connecting part by a locking fastener.

[0028] As a preferred embodiment, the PCB board is also electrically connected to unlock and lock indicator lights, with the lit ends of the unlock and lock indicator lights exposed outside the lock body.

[0029] As a preferred embodiment, the lock body includes a lock base, an outer cover, and a top cover. The outer cover is fitted onto the lock base. The lock base is provided with a first mounting position, a second mounting position, and a third mounting position. The mechanical unlocking mechanism is installed in the first mounting position, and the lock cylinder is exposed on the outer cover. The bolt mechanism is installed in the second mounting position, and the knob is exposed outside the outer cover. The electronic unlocking mechanism is installed in the third mounting position, and the NFC antenna board is placed inside the top cover.

[0030] As a preferred embodiment, the lock seat also contains a battery, which is electrically connected to the PCB board.

[0031] As a preferred embodiment, the unlocking / locking sensing element is an unlocking Hall element, and the locking / locking sensing element is a locking Hall element.

[0032] Compared with existing technologies, this invention has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves this through the structural design and coordination between the latch mechanism, knob, mechanical unlocking mechanism, and electronic unlocking mechanism. In the mechanical key unlocking state, the lock cylinder is rotated by the key, causing one end of the linkage lever to move away from the rotating shaft, thus disengaging one end of the movable pin from the lever. Rotating the knob unlocks the lock, and the rotating shaft can rotate relative to the lock seat. In the electronic unlocking state, the motor receives a control signal and drives the cam to rotate. At this time, rotating the knob unlocks the lock, causing the rotating shaft to rotate. The movable pin moves backward under the rotational force of the rotating shaft, pushing the slider backward, causing the magnet to approach and trigger the unlocking and locking sensing element. In this way, multiple unlocking methods can be used in combination, including electronic and mechanical key unlocking. People can flexibly choose the unlocking mode as needed, thereby improving the stability of the lock and the user experience.

[0033] In particular, its simple structure and stable and reliable mechanical and electronic unlocking modes utilize the linkage structure between the movable pin and the lever and slider respectively, resulting in precise and fast unlocking with high reliability. Furthermore, the entire lock has a compact spatial arrangement, making it suitable for widespread application.

[0034] Then there's the cooperation between the unlocking / locking sensing element, the locking / locking sensing element, and the magnet. When the knob is turned to unlock or lock, the magnet moves closer to trigger the corresponding unlocking / locking sensing element as the knob rotates. In this state, any unlocking or locking request will not be responded to, thus avoiding damage to the motor caused by stalling due to accidental touch.

[0070] Please refer to Figures 1 to 10 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0071] A smart locker lock includes a lock body 10, a bolt mechanism 20, a knob 30, a mechanical unlocking mechanism 40, and an electronic unlocking mechanism 50.

[0072] Preferably, the lock body 10 includes a lock base 11, an outer cover 12, and a top cover 13. The outer cover 12 covers the lock base 11. The lock base 11 is provided with a first mounting position, a second mounting position, and a third mounting position. The mechanical unlocking mechanism 40 is installed in the first mounting position, and the lock cylinder 41 is exposed outside the outer cover 12. The bolt mechanism 20 is installed in the second mounting position, and the knob 30 is exposed outside the outer cover 12. The electronic unlocking mechanism 50 is installed in the third mounting position, and the NFC antenna board 51 is placed inside the top cover 13. Preferably, a battery is also provided inside the lock base 11, and the battery is electrically connected to the PCB board 52.

[0073] The latch mechanism 20 is disposed on the lock body 10. The latch mechanism 20 includes a rotating shaft 21, a movable pin 22, and a latch 23. The rotating shaft 21 is provided with a mounting groove 211, which extends axially along the rotating shaft 21. The movable pin 22 is movably disposed in the mounting groove 211, so that one end of the movable pin 22 protrudes outside the rotating shaft 21. The latch 23 is connected to one end of the rotating shaft 21 and protrudes outside the lock body 10. Preferably, the rotating shaft 21 includes a shaft body 212 and a rotating part 213 and a connecting part 214 disposed on the shaft body 212.

[0074] The knob 30 is externally provided with a magnet 31 for cooperating with the unlocking / locking sensing element 56 or the locking / locking sensing element 57; the knob 30 is rotatably connected to the other end of the rotating shaft 21, and the knob 30 controls the rotating shaft 21 to rotate selectively, thereby driving the bolt 23 to rotate to realize the opening and closing of the lock; the knob 30 is rotatably connected to the rotating part 213, and the bolt 23 is locked to the connecting part 214 by a locking fastener.

[0075] The mechanical unlocking mechanism 40 is located beside the bolt mechanism 20; the mechanical unlocking mechanism 40 includes a lock cylinder 41 and a lever 42, the lever 42 being selectively abutted against the outside of the rotating shaft 21 via the lock cylinder 41; the lock cylinder 41 is rotatably mounted on the lock body 10, such that the end of the lever 42 near the rotating shaft 21 is close to or away from the rotating shaft 21;

[0076] Preferably, the lower end of the lock cylinder 41 is provided with a protrusion 411, and the lever 42 includes a left connecting section 43 and a right connecting section 44. The left connecting section 43 is provided with a movable groove 431 on the side near the protrusion 411. The movable groove 431 has a left mating end 432 and a right mating end 433.

[0077] The right connecting section 44 is provided with a first arc-shaped abutment part 441 for abutting and cooperating with the outer periphery of the rotating shaft 21 and a stop part 442 for abutting and cooperating with the front end of the movable pin 22 on the side facing the rotating shaft 21. The first arc-shaped abutment part 441 is recessed on the right connecting section 44, and the stop part 442 is located beside the first arc-shaped abutment part 441.

[0078] When the lock cylinder 41 rotates, the protrusion 411 slides against the right mating end 433, causing the right connecting section 44 to shift to the left, so that the first arc-shaped abutment part 441 and the stop part 442 move away from the rotating shaft 21 and the movable pin 22 respectively. By utilizing the cooperation between the protrusion 411 and the movable groove 431, the lever 42 is moved to form a locking or unlocking mechanism between the lever 42 and the rotating shaft 21 and the movable pin 22. When locked, the first arc-shaped abutment part 441 and the stop part 442 are used to position and lock the rotating shaft 21 and the movable pin 22. Its structure is ingeniously designed, and the lock is reliable and highly secure.

[0079] The electronic unlocking mechanism 50 is disposed on the lock body 10. The electronic unlocking mechanism 50 includes an NFC antenna board 51, a PCB board 52, a motor 53, a cam 54, a slider 55, an unlocking and locking sensing element 56, and a locking and closing sensing element 57.

[0080] The motor 53 drives the cam 54 to rotate and is electrically connected to the PCB board 52; the slider 55 is disposed between the rotating shaft and the cam 54, and an elastic element 58 is connected between the cam 54 and the slider 55; the slider 55 can selectively move back and forth; wherein, one side of the slider 55 abuts against the rotating shaft 21.

[0081] Preferably, the cam 54 includes a first front connecting section 541 and a first rear connecting section 542, the output end of the motor 53 is connected to the first rear connecting section 542, and the first front connecting section 541 includes a main body 543 and a limiting part 544 extending from one side of the main body 543; preferably, the main body 543 is also provided with a positioning hole 545, a steel ball 546 is provided in the positioning hole 545, one end of the elastic member 58 abuts against the steel ball 546, and the other end of the elastic member 58 abuts against the rear side of the second front connecting section 551.

[0082] The slider 55 includes a second front connecting section 551 and a second rear connecting section 552. The second rear connecting section 552 extends from the rear end of the second front connecting section 551. The second front connecting section 551 is recessed with a second arc-shaped abutment portion 553, which faces the mounting groove 211.

[0083] In the electronic unlocking state, the limiting part 544 is away from the second rear connecting section 552, and the second arc-shaped abutting part 553 is away from the rotating shaft 21; in the electronic locking state, the second arc-shaped abutting part 553 abuts against the rear side of the mounting groove 211, and the second rear connecting section 552 abuts against the limiting part 544; in the locking state, it cooperates with the lever 42 to form a double positioning and locking of the rotating shaft 21 and the movable pin 22.

[0084] The NFC antenna board 51 is electrically connected to the PCB board 52; the unlocking / locking sensing element 56 and the locking / locking sensing element 57 are disposed on the PCB board 52 and located below the knob 30, and the PCB board 52 is electrically connected to the unlocking / locking sensing element 56 and the locking / locking sensing element 57; preferably, the PCB board 52 is also electrically connected to unlocking and locking indicator lights, and the lit ends of the unlocking and locking indicator lights are exposed outside the lock body 10. Preferably, the unlocking / locking sensing element 56 is an unlocking Hall effect sensor, and the locking / locking sensing element 57 is a locking Hall effect sensor.

[0085] In this embodiment, the locking and unlocking of the lock can be monitored in real time through the PCB board 52 with integrated Bluetooth module, improving the reliability of the lock.

[0086] In the locked state, the lever 42 and the slider 55 abut against the outside of the rotating shaft 21, and one end of the movable pin 22 abuts against the lever 42; the magnet 31 approaches the locking sensor 57, thus preventing the knob 30 from rotating the rotating shaft 21.

[0087] like Figure 7 As shown, it illustrates a schematic diagram of the lever moving away from the rotating shaft in the mechanical key unlocking state. In the mechanical key unlocking state, the lock cylinder 41 is rotated by the key, so that one end of the lever 42 moves away from the rotating shaft 21, causing one end of the movable pin 22 to disengage from the lever 42. The knob 30 is turned to unlock, and the rotating shaft 21 can rotate relative to the lock seat.

[0088] like Figure 8 As shown, it illustrates a schematic diagram of the limiting part moving away from the rotating shaft when the cam rotates in the electronic unlocking state. In the electronic unlocking state, the motor 53 receives a control signal and drives the cam 54 to rotate. At this time, rotating the knob 30 to unlock causes the rotating shaft 21 to rotate. The movable pin 22 moves backward under the rotational force of the rotating shaft 21, pushing the slider 55 to move backward, so that the magnet 31 approaches the unlocking and locking sensing element 56.

[0089] The working process of this embodiment is described in detail below:

[0090] In the locked state, the protrusion 411 abuts against the left mating end 432, the front end of the movable pin 22 is restricted by the stop part 442, the second arc-shaped abutting part 553 abuts against the rear side of the mounting groove 211, and the second rear connecting section 552 abuts against the limiting part 544; the magnet 31 approaches the trigger locking sensing element 57, so that the knob 30 cannot drive the rotating shaft 21 to rotate;

[0091] When the lock cylinder 41 is rotated in the mechanical key unlocking state, the protrusion 411 slides against the right mating end 433; causing the right connecting section 44 to move to the left, so that the first arc-shaped abutment part 441 and the stop part 442 move away from the rotating shaft 21 and the movable pin 22 respectively, so as to form the paddle 42 to unlock the rotating shaft 21 and the movable pin 22.

[0092] In electronic unlocking mode, the NFC antenna board 51 receives a signal and sends it back to the PCB board 52. The PCB board 52 controls the motor 53 to rotate the cam 54, causing the limiting part 544 of the cam 54 to move away from the second rear connecting section 552 of the slider 55, providing space for the slider 55 to move. At this time, turning the knob 30 to unlock causes the rotating shaft 21 to rotate. The movable pin 22 moves backward under the rotational force of the rotating shaft 21, pushing the second arc-shaped abutment part 553 of the slider to move backward to complete the unlocking. At this time, the magnet 31 approaches the unlocking and locking sensing element 56 to form a lock, so as to avoid accidental touch.

[0093] The key design feature of this invention lies in the structural design and coordination between the latch mechanism, knob, mechanical unlocking mechanism, and electronic unlocking mechanism. In the mechanical key unlocking state, the lock cylinder rotates via the key, causing one end of the linkage lever to move away from the rotating shaft, disengaging one end of the movable pin. Turning the knob unlocks the lock, allowing the rotating shaft to rotate relative to the lock seat. In the electronic unlocking state, the motor receives a control signal and drives the cam to rotate. Turning the knob unlocks the lock, causing the rotating shaft to rotate. The movable pin moves backward under the rotational force of the shaft, pushing the slider backward, bringing the magnet closer to trigger the unlocking / locking sensing element. This allows for the combined use of multiple unlocking methods—electronic and mechanical key unlocking—allowing users to flexibly choose the unlocking mode as needed, thereby improving the stability of the lock and the user experience.

[0094] In particular, its simple structure and stable and reliable mechanical and electronic unlocking modes utilize the linkage structure between the movable pin and the lever and slider respectively, resulting in precise and fast unlocking with high reliability. Furthermore, the entire lock has a compact spatial arrangement, making it suitable for widespread application.

[0095] Then there's the cooperation between the unlocking / locking sensing element, the locking / locking sensing element, and the magnet. When the knob is turned to unlock or lock, the magnet moves closer to trigger the corresponding unlocking / locking sensing element as the knob rotates. In this state, any unlocking or locking request will not be responded to, thus avoiding damage to the motor caused by stalling due to accidental touch.

[0096] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
